Workbench Mechanical defines creep limit ratio to 1 as a default value. It is a ratio of equivalent creep strain increment and the modified equivalent elastic strain Creep Limit Ratio is the maximum allowable limit to the creep Strain Ratio. If, during a timestep, the solver calculates a Creep Strain Ratio larger than the Creep Limit Ratio (default =1.0), then the solution is automatically bisected until the creep limit is satisfied or the minimum time step is reached. Although WB-Mechanical sets this limit to 1.0 by default, a creep limit ratio of 0.1 to 10 (10-1000%) is generally recommended, depending on the magnitude of the equivalent elastic strain developed and the level of accuracy required.
